Second Life for Server Components

Servers consume energy, not just in data centers but also in their creation—mineral extraction and manufacturing takes energy. To alleviate these costs, Carnegie Mellon researchers are finding ways to re-use old server components without sacrificing performance.

This is essentially a glorified article about not needing the latest and greatest, and limiting shortcomings with the right combinations of used components and software. Nothing groundbreaking, but hopefully represents a slowly shifting zeitgeist into saving energy and carbon emissions. The Researchers estimate their methods would reduce global emissions by 0.2%.
